Leakage from Piston Seals in Undamaged Pump When the pressure washer runs and allows the water in without spraying water, the water heats up. But if the water becomes extremely hot, the thermal release valve can get damaged, causing leakage and pressure loss. How to Fix – Leakage can also take place because the press fit/screws are not working correctly. Or, the O-ring of the hose might be broken or damaged. How to Fix –If your Karcher pressure washer leaks water from the bottom, it might be because of damage in the thermal release valve due to overheating. This valve maintains water temperature by recirculating water and releasing excessively hot water.

In that case, the coupling and the seal will have to be replaced. The process of replacing the connector is extremely easy. I asked a question on here about 3 or 4 months ago, as having not used my pressure washer for some months it had started leaking. It made a rattling noise when I moved it. It was suggested the fault might be the O Rings. I have a Karcher extension hose between the front of the unit and the pressure gun. That has seized onto the pressure washer, and however hard i try i cannot shift it. As a result I hadn't got round to stripping the washer. The outlet seal is at the connection between the pump and the high-pressure washer hose that pushes water to the trigger wand. This point of attachment is similar to that of the inlet connection in structure, complete with couplings and outlet seals.

This makes it suitable for cleaning all around the home, such as fencing, garden furniture and vehicles.If the couple is damaged, it will need to be replaced the same way as the inlet cover – and if the coupling is intact, the O ring inside needs replacing. O rings are easily available, and the replacement process is pretty straightforward. The pump and switch assembly are clamped to the motor assembly with screws that need to be undone. You will then have to remove the inlet and outlet, held in place with metal forks. The labelling on the lance (3 - Hard, 2 - Medium, 1 - Soft and Mix - for detergent application) relate to use with a Karcher G145 Q Power Control Gun as the gun will display the pressure setting in relation to the labelling. But here’s a word of warning! If you’re not experienced in handling hardware or don’t feel confident, don’t wing it. If your Karcher device is still within its warranty period, it’s better to take advantage of the company’s customer support system. If there’s water in your washer’s engine oil, the faulty oil seal will need to be changed. For that, you must disassemble the pump assembly to detach the pump from the piston housing.
